ADP-0241-05A - Installation Instructions

INSTALLATION OF THIS ADAPTOR SHALL BE IN ACCORDANCE WITH THE REQUIREMENTS OF THE AUTHORITIES HAVING JURISDICTION

Refer also to HOYME Installation Instructions: Combustion Air Control Damper, Series HOM; Replacement/Ventilation Air Control Damper, Series HAC; and Adaptor ADP- 1101- 05A.

ADP-0241-05A

4” x 5” x 2 1/2” (101 x 127 x 64 mm)

This Relay Adaptor may be used as an automatic switch having a 24Vac Coil and 120Vac points to control a line voltage circuit for up to a 5 amp draw such as a 120Vac exhaust fan. It can also be used 100% for 24Vac switching. (See wire diagrams on next page.)

A typical application where all the points are used for
24Vac switching may occur when dry points are used at the exhaust fan switch.
When the exhaust fan switch is turned on, the furnace fan and the fresh air
damper, if used, will open simultaneously. The fresh air damper, however, will not open for furnace firing.

If the
damper is required to open when the appliance fires:

a) Refer
to wiring diagram (next page) showing the
Power Close Damper with Relay;

- or -

b) Use a regular fresh air damper with an ADP-0242-05A and follow its
Installation Instructions;

- or -

c) If controlled
line voltage is available from the exhaust fan, use Adaptor ADP-1102-TWP and follow
its installation instructions.

Fitness of this Adaptor/Damper combination to satisfy air supply requirements for fuel fired appliances during operation of the

Inter-connected exhaust fan(s) shall be investigated by the enforcing authorities.

Note:For PC damper only, a toggle switch in series with 24Vac electrical supply line to the Damper will cause it to open as required.

* Note:For PC damper without relay and if adding a Combustion Air Damper, re-connect Fresh Air Damper from furnace ‘C’ to Green wire of the Combustion Air Damper. Both dampers will open during firing of the furnace.

* Note:If existing ventilation relay (auxiliary relay switch) cannot be located, relay wires presently connected to ‘R’ and ‘G’ of the furnace are to be re-connected to ‘3’ of ADP and ‘C’ of the furnace. ADP ‘WHT’ will then go to ‘GF’ of the furnace and ADP ‘RED’ will go to ‘GT’ of the thermostat, (if used).
